4.4.2 Flashing the Bootloader
Use a bootable SD card in order to boot into Barebox.
Without any valid bootloader in NAND, the board will automatically try to
use the SD card for booting. Otherwise you need to force booting from SD
card by switching DIP switch S4 to
ON ( 3.2.8 ).
The partition
boot on the SD card should automatically be mounted as directory /boot by
the Barebox. Otherwise you can mount it manually using the following Barebox commands:
mkdir /boot
mmc0.probe=1
mount /dev/mmc0.0 /boot
ƒ
Flash x-loader MLO by typing:
barebox_update ‐ t MLO.nand /boot/MLO
ƒ
Write the Barebox into the Flash by typing:
barebox_update ‐ t nand /boot/barebox.bin

cp /boot/linuximage /dev/nand0.kernel.bb
